171456: If a divorced woman remarries, who gets custody of the daughter?

I divorced my husband (through khula issued by a group of Imams in our community as my ex-husband was refusing to accept the khula due to his difficult personality). The reason why I asked for the khula was because he refused to financially support me or our daughter and was very negligent towards us. My daughter was less than one years old at the time. For one year, the Imams tried to negotiate a contract with him, but because he is argumentative and very unreasonable, the Imams encouraged me to go to American court so that I could get some financial support for our daughter. I despised going to the American court, but I really felt that I had no other options. I only take what is Islamically reasonable in terms of money for my daughter from my ex-husband. We have a visitation schedule in place, but he only spends minimal time with her and makes very little effort to establish a good relationship with her.
My daughter is now 7 years old and has always lived with me and my parents. I would like to re-marry and have a question about custody. I know that once a woman re-marries, she loses custody of her child. However, my daughter is now 7 years old and old enough to say who she wants to be with. I know there is a difference of opinion as to who can “sponsor” her, but if she really wants to live with me, can she continue to do so after I remarry. Please note that the man I would like to re-marry has absolutely no problems with helping me raise her. Also, although my ex-husband is Sunni Muslim, his entire family is either non-Muslim or Shiaa. Given that I know my ex-husband tends to be negligent, I don’t want to put my young daughter in an un-Islamic environment.
In the event that I do lose primary custody of my daughter, could my mother “sponsor” her. Also, what happens after the age of puberty? Can she then come back to live with me?.

Praise be to Allaah.

Firstly:

The mother has more right to custody of her children until
the age of seven, so long as she has not remarried, because of the report
narrated by Ahmad (6707) and Abu Dawood (2276), from ‘Abdullah ibn ‘Amr,
according to which a woman said: O Messenger of Allah, this is my son; my
womb was a vessel for him, and my breasts gave him to drink, and my lap was
a protection for him. His father has divorced me and he wants to take him
away from me. The Messenger of Allah (blessings and peace of Allah be upon
him) said: “You have more right to him so long as you do not remarry.”

This hadeeth was classed as hasan by al-Albaani in Saheeh
Abi Dawood.

If she remarries, custody passes to the one who comes after
her. There is a difference of opinion among the fuqaha’ concerning that.
Some of them think that it passes to the maternal grandmother and this is
the opinion of the majority of the four madhhabs. Some think that it passes
to the father, and this is the view favoured by Shaykh al-Islam Ibn Taymiyah
and Ibn al-Qayyim. See al-Masoo‘ah al-Fiqhiyyah, 17/303; ash-Sharh
al-Mumti‘, 13/535.

It says in Zaad al-Mustaqni‘: The one who is most
entitled to it (custody) is the mother, then her foremothers, the closest
then the next closest, then the father, then his foremothers in like manner,
then the grandfather, then his foremothers in like manner…

Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said in
his commentary: This sequence that was mentioned by the author is not based
on any foundation of evidence and there is no rational explanation for it,
and there are some contradictions in it that make one feel uneasy about it.
Hence the scholars differed concerning the sequence of (who is entitled to)
custody and there are several opinions, but none of them has any reliable
basis. Hence Shaykh al-Islam (may Allah have mercy on him) was of the view
that custody should go to the one who is most closely related, whether that
is the father or mother, or on the father’s side or on the mother’s side; if
they are equal, then priority should be given to the female. If there are
two males or two females then lots may be drawn, otherwise the father’s side
takes precedence.

End quote from ash-Sharh al-Mumti‘, 13/535

However, even though the father may take precedence over the
maternal grandmother, it is still essential to examine the father’s
situation and how suitable and able he is to raise the child. If he is
corrupt or incapable of raising the child, then custody passes to someone
else. These are matters that should be solved through the intervention of
good and righteous people in order to choose what is best for the child and
less harmful to both the husband and wife.

Secondly:

If the mother has not remarried and the child has reached the
age of seven years:

-1-

If the child is male, he should be given the choice between
his father and mother and then live with the one he chose, because of the
report narrated by an-Nasaa’i (3496) and Abu Dawood (2277), according to
which a woman came to the Messenger of Allah (blessings and peace of Allah
be upon him) and said: May my father and mother be sacrificed for you. My
husband wants to take my son away even though he benefits me and brings me
water from the well of Abu ‘Anbah. Her husband came and said: Who is
disputing with me concerning my son? [The Prophet (blessings and peace of
Allah be upon him)] said: “O boy, this is your father and this is your
mother, take the hand of whichever of them you want.” And he took his
mother's hand and she went away with him.

This hadeeth was classed as saheeh by al-Albaani in Saheeh
Abi Dawood. This is the opinion of the Hanbalis and Shaafa‘is

-2-

If the child is female, then she is also to be given the
choice according to ash-Shaafa‘i (may Allah have mercy on him).

Abu Haneefah said: The mother is more entitled to custody
until the girl gets married or starts to menstruate.

Maalik said: The mother is more entitled to custody until she
gets married and the husband consummates the marriage with her.

Ahmad said: The father is more entitled to custody, because
it is more appropriate for the father to take care of her.

See: al-Mawsoo‘ah al-Fiqhiyyah, 17/314-317

Thirdly:

If the child has reached the age of maturity that he may
choose whichever of his parents he wants.

Ibn Qudaamah (may Allah have mercy on him) said:

There is no proof of custody except in the case of a child or
one who has a disability. As for the adult of sound mind, there is no
custody of him and he has the choice of staying with whichever of his
parents he wants, and if he is a man he has the option of staying alone and
being independent of both of them. But it is not recommended for him to stay
away from both of them or to stop honouring them. If the child is a girl
then she has no option of staying alone and her parents have the right to
prevent her from doing that, because there is no guarantee that she will be
safe from someone who will enter upon her and do her harm and bring shame
upon her and her family; if she has no father than her guardian and family
have the right to prevent her from doing that.
